To the Editor:
—In a reply to an inquiry regarding intradermal vaccination (The Journal, January 17, p. 223) occurs the sentence, "To class the Force method with the intradermal method is likely to be confusing, for his description of the method used appears to be subcutaneous rather than intracutaneous."I have never published a description of the method used at this university, and I am at a loss to determine on what this opinion is based. Recently I sent a personal communication to Dr. J. C. Geiger of the University of Chicago, giving directions for intradermal vaccination, in which these words occur: "The needle should not enter the subcutaneous tissue, and the bevel should not show through the epidermis. The proper site for an intradermal smallpox vaccination is neither subcutaneous (as in the ordinary hypodermic injection), nor subepidermal (as in the Schick test), but intradermal." I might further amplify this
